MAROEL M. TREMBLAY, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO PIERRE LUSSIER, J R., OF SAME PLACE.

SWITCH-OPERATING MECHANISM FOR CARS.

SPECIFICATION forming part of Letters Patent No. 594,715, dated November 30, 1897.

Application filed July 23, 1897. Serial No. 645,751. (No model.)

Be it known that I, MAROEL M. TREMBLAY, a subject of the Queen of Great Britain, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Switch-Operating Mechanism for Cars, of which the following is a specification.

This invention relates to mechanism or equipments on street-railway cars for operating switches of the general character illusissued to me and Pierre Lussier, J r., August 18, 1896, No. 566,281.

The object of the present invention is to simplify the switch-operatin g mechanism generally and to render the same more positive and certain in its operation in relation to the different switches along the railway, all substantially as will hereinafter be rendered man ifest; and the invention consists in the constructions and combinations of parts, all substantially as will hereinafter fully appear, and be set forth in the claims.

Reference is to be had to the accompanying drawings, in which the improvements are illustrated, and in which Figure 1 is a front elevation, with parts broken away and in vertical section, of the railway-car and the switch-operating mechanism thereon. Fig. 2 is a sectional elevation of the same. Fig. 3 is a plan view of parts of the mechanism as seen below the plane indicated by the section-line 33, Fig. 1. Fig. 4 is a plan view of parts in detail to be hereinafter referred to.

Similar characters of reference indicate cor- In the drawings, A represents the platform of a street-railway car, on the under side of which and on opposite sides of the center thereof are secured the brackets B B, consisting of uprights a and the lower crossplates 1).

E designates vertical members of a frame or support which is of an angular form and comprising the horizontal portions K, in the depending members 0 c of which are slideways (1 d. The vertical portions of the parts E are passed upward loosely through thel1ori zontal bottoms b of the aforesaid brackets B U represents a rack-bar supported horizontally to slide in suitable ways thereforin the lower ends of the brackets or hangers o c, which are secured to and depend below the platform.

w 03 are connecting-rods which are secured to the ends of the rack -bar U and also engaged with the aforesaid slides G G, the en'- gagement being constituted by the downturned ends 00 of the rods x,which are passed through sockets or eyes :6 therefor in the slides, all so that the end thrust of the rods 00 00 will effect sliding movements of the said slides G, but so that when the slides are depressed bodilyas the frames E K are lowered under the foot-pressure at F these lowering movements and the return movements may be accomplished without interference by the rods 00. In mesh with the said rackbar U is a pinion-wheel t, which is affixed at the lower end of the vertical shaft T, which extends up through and above the platform at the front middle portion of the latter, a crankhandle or operating-arm V being affixed on the upper end of this shaft.

This said shaft T passes loosely up through a fixed metallic disk or dial W, having thereon graduations, as indicated in Fig. 4, the shaft T being provided with an index finger or pointer w. The purpose of these appliances is to enable the motorman or car driver to know just how far on a given turning of the handle V and rotational movement of the shaft T the rack-bar U causes a projection of the switch-operating tongues H H, and by having the graduations shown on the dialW so made as to represent inches and halfinches it becomes very easy for the motorman to project the proper one of the side switch-operatin tongues H exactly over the point of impingement of the switch before the same is reached and before the tongue is lowered, so that the same may be properly and with certaint-yengaged, the engagement of the switch-tongue and its operation or shifting by the tongue II being accomplished in the same manner as described in the aforementioned patent.

Of course it is apparent from the illustrations of the mechanism here given that when one switch-operating tongue 11 is moved out ward in position to operate the switch the similar tongue at the other side is moved inward in a corresponding degree by reason of both of said tongues being connected to the same rack-bar.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a switch mechanism for cars, the combination with laterally-movable switch-operating tongues or members and Vertically-movable and spring-sustained supports on which said members are mounted, of a vertical shaft mounted on the car to rotate, connections between said shaft and the switch-operating members whereby when the shaft is rotated, said members will be correspondingly laterally moved, a graduated dial and pointer provided in relation to said shaft whereby the extent of the lateral movement of the said switch -operating members may be determined, and means for depressing the supports for said members, substantially as described.

2. In a switch mechanism for cars, the combination with laterally-movable switch-operating tongues or members and vertically-movable and spring-sustained supports on which said members are mounted, of a vertical shaft mounted on the car to rotate, and having the pinion, a rack-bar in mesh with said pinion and transversely movable, the rods connecting said rack-bar and said switch-operating members, a graduated dial and pointer provided in relation to said shaft whereby the extent of the lateral movement of the said switch operating members may be determined, and means for depressing the supports for said members, substantially as dcscribed.

3. In a switch-operating mechanism for cars, the combination with the laterally-movable switch-operating tongues or members and vertically-movable and spring-sustained supports on which said members are mounted, of the vertical shaft T mounted on the car to rotate and having the pinion t, handleV and pointer w, the graduated dial W supported on the car through which said shaft passes, the rods 00 :0 connecting the opposite ends of said rack bar with said switch operating members, and means for depressing the supports for said members, substantially as described.

I testimony that I claim the foregoing as my invention I have made my mark, in presence of two witnesses, this 22d day of May, 1897.
